Abstract

The invention relates to a cold cathode electronic gun control system and a control method. The cold cathode electronic gun control system comprises a controller, an input end connected with the controller, a hydrogen controller, an oxygen controller, an upper focusing end, a lower focusing end, an X scanning end and a Y scanning end. The raw material melts into the liquid state through controlling the hydrogen controller, the oxygen controller, the upper focusing end, the lower focusing end, the X scanning end and the Y scanning end by the controller. The cold cathode electronic gun control system adopts an cold cathode electronic gun, is simple in circuit structure, fewer in failure and low in cost. All component interfaces are in modularized design and easy to change and maintain. Software and hardware are in humanization design, have low requirements for the level of operating staff and can meet smelting and purification of continuously industrialized refractory metal.

Description

technical field [0001] The invention relates to a control system, in particular to a cold cathode electron gun control system and a control method thereof, belonging to the field of smelting. Background technique [0002] The high-energy electron beam emitted by the electron gun converts kinetic energy into heat energy for metal smelting technology, which is widely used in the smelting and purification of expensive and refractory metals. [0003] Electron guns are mainly heat guns. The cathode of the hot cathode gun adopts a tungsten wire structure, and the cathode of the electron gun needs to be heated above 2000°C during the working process to speed up the escape of electrons, so the energy consumption is high. [0004] The cathode of the cold cathode gun is made of aluminum block. It does not need to heat the cathode of the electron gun during operation, only hydrogen and oxygen need to be fed. Due to the extra filament and accelerated anode of the heat gun, the control...
